KANSAS CITY (AP) - A University of Missouri-Columbia researcher says he has isolated a rare type of adult stem cell from the blood of pigs, in a procedure that could some day be used on adults. Molecular biologist Elmer Price says after he and two colleagues isolated the stem cells, they used chemical signals to convert them into neurons, bone cells, fat cells and two kinds of blood vessel cells. Price says his research is not related to stem cells from human embryos, a type of research that has sparked debate across Missouri. He says he still supports research on human embryos and adult stem cells. But Jaci Winship, executive director of Missourians Against Human Cloning, says Price's findings are another example of why research on embryonic stem cells isn't needed.
